How does the Set Level Visibility editor node work?

Hey all,

The project I’m working on has a lot of different sub-levels. To make navigation easier, I wanted to use the editor widget tool to make a button/slider or something, which would easily make certain levels visible, while disabling the others. The logic for it should be quite easy, but I don’t know how this “Set Level Visibility” node should work.

It takes in a “Level object” reference, but I have no idea what this is or how to get it. It’s not the same as the “Level Streaming Object” reference. So anyone know how to get this object?
